1 Claim. (Cl. 198-121) My invention relates to new and usefulimprovements in grain augers, and in particular to the supporting memberextending between the wheels and the auger tube, an object of myinvention being to provide a device of the character herewithindescribed wherein this supporting member is adjustable as to lengththereby widening the scope of the angle of inclination of the augerconsiderably.

A further object of my invention is to provide a device of the characterherewithin described in which said adjustment is simple to undertake andwhich furthermore provides rigid support at the junction of the twocomponents at all times.

Another object of my invention is to provide a device of the characterherewithin described which is simple in construction, and otherwise wellsuited for the purpose for which it is designed.

With the foregoing objects in view, and such other objects andadvantages as will become apparent to those skilled in the art to whichthis invention relates as this specification proceeds, my inventionconsists essentially in the arrangement and construction of parts all ashereinafter more particularly described, reference being had to theaccompanying drawings in which:

Figure 1 is a perspective View of my device.

Figure 2 is an enlarged perspective view of the junction between the twocomponents of the adjustable supporting member.

Figure 3 is an enlarged perspective view showing the attachment of thesupporting member to the grain auger tube.

Figure 4 is an enlarged transverse section taken through the line 4 4 ofthe Figure 2.

In the drawings like characters of reference indicate correspondingparts in the diiferent figures.

The range of the angle of inclination of a conventional grain auger isrelatively limited and in order to extend this range it is necessary toincrease the length of track and the length of the supportingcomponents. However, this is not always convenient particularly withcertain type of grain augers which are designed to lower to the extentnecessary in order that they may be towed behind vehicles.

In other words, the average conventional grain auger is a, compromisebetween towing facilities and high angle of elevation.

My invention overcomes these disadvantages by providing a supportingmember which is adjustable as to length thereby increasing materiallythe range of the angle through which the auger may be elevated.

Proceeding now to describe my invention in detail, it will be seen uponreference to the accompanying drawings that I have illustrated a grainauger comprising an auger tube 1 having an auger flight (notillustrated) therewithin driven by drive shaft 2 from a gear box 3 whichin turn is driven from a source of power (not illustrated) supportedupon motor platform 4. The auger tube is supported upon a pair of wheels5 carried upon an axle beam 6, a pair of braces 7 extending from thebeam to the gear box 3 and a further supporting member collectivelydesignated 8 extending from the beam to the upper end 9 of the tube thusforming a triangle consisting of the tube, the members 7, and the member8. Means are provided to alter the relative angle between the members 7and 8 and consist of a winch 10 mounted on member 8, said winchactuating a cable 11 passing over sheaves 12 and 13 and thence to a xedpoint 14 upon the underside of the tube 1 so that rotation of the crankwill cause the angle to vary and, in conjunction with means hereinafterto be described, permit the upper end of the member 8 to slide down thetube.

This means takes the form of a track 14 secured to the underside of thetube, said track being slidablyr engagable within claws 15 secured uponthe upper end of member 8 together with a roller 16 journalled betweenthe claws and upon which the track rests.

From the foregoing, it will be appreciated that the angle of inclinationof die tube 1 with the horizontal may be varied by rotation of the crankcausing the track to slide within the claws 15.

The member 8 is made adjustable in length in order to increase the rangeof operation of the device and in order to obtain this adjustment, itwill be seen that the member 8 consists of a lower component in the formof an A frame 15', the lower ends of which are secured to the beam 6.The apex 16 of the A frame is formed from a relatively short length offlattened channel material 17, the side anges 18 of which act as bearingsupports for the upper tongue component 19 of the member 8. This tonguecomponent (upon the outer end of which the claws 15 are secured) alsoconsists of a relatively flat channel member which nests between theflanges 18 of the portion 17, said tongue being apertured along thelength thereof as indicated by the reference character 20.

A bolt and nut assembly 21 extends through an aperture in the channel 16and through any one of the apertures 20 within the tongue thus locatingthe A frame 15 in relation to the tongue 19 as desired. This securing ofthe two components together, is reinforced by the provision of a furthernut and bolt assembly 22 which passes through a brace 23 spanning the Aframe adjacent the apex thereof and through the aperture in the tongueimmediately therebelow.

From the foregoing, it will be appreciated that the effective length ofthe component 8 may be varied within limit readily and easily asdesired.

Since various modications can be made in my invention as hereinabovedescribed, and many apparently widely different embodiments of same madewithin the spirit and scope of the claim without departing from suchspirit and scope, it is intended that all matter contained in theaccompanying specification shall be interpreted as illustrative only andnot in a limiting sense.

What I claim as my invention is:

In a wheel mounted grain auger including an auger tube, an auger flighttherewithin, and a transverse axle beam, a supporting member extendingbetween one end of said tube and said axle beam, and means to adjust thelength of said supporting member, said supporting member including alower A frame component secured at the lower ends thereof to said axlebeam, and an upper tongue component adjustably attached at one end toadjacent the apex of said A frame and at the other end, to the upper endof said auger tube, the apex of said A frame consisting of a attenedchannel, said tongue also being formed of a attened channel, the channelforming said apex overlapping said tongue and acting as a bearingtherefor, bolt means extending through said apex and said tongue andfurther bolt means extending through said tongue and a brace spanningsaid A frame adjacent the apex thereof.
